the lenses before the eyes of the wearer and two temples, one right and one left, for the purpose of holding the front in correct posi-' tion on the face of the wearer.

In accordance with the general custom, these temples, or side pieces, are attached to the outer edge of the rims holding the lenses at a point coincident with the points at which a horizontal plane passing through the pupils of the eyes of the'wearer cuts the outer edge of said rims. As a consequence of this meth- 0d of construction the materials of the temples is on the same horizontal plane with the pupils of the eyes of the wearer, with the result that should the wearer endeavor to obtain a vision of an object on either side, without first turning his head so as to obtain a direct line of vision of said object, his vision is impeded to the extent to which the material of which the temples or side pieces are composed interferes with his line of vision.

As will be readily seen in cases where, as is now in very common use, the spectacle frames are composed of horn, shell, celluloid products, or other material necessitating temples of heavy construction so as to secure the desired strength and rigidity, this interference may prove to be a serious bar to side vision, and. in the case of crossin of modern city streets, at right angles to the line of traffic, may result in serious danger to the life and limb of the wearer as the result of his inability toobtain a clear view of approaching automobiles and other moving objects, which owing to the dark field caused on either side of the wearer as the result of the interference of he temple material with his side vision, rm thus given an opportunity to come upon much wearer from either side, within the area of such dark field, without the wearer being I warned of their approach.

In order to eliminate this dark field, thereby securing to the spectacle or goggle wearer an unimpeded side field of vision, as is the case with the natural eye, I have invented a spectacle frame in which the point of attachment of the temples or side piecesto the front is raised to a point substantially above the points at which the horizontal plane passing through the pupils of the eyes of the wearer cuts the outer edge of the rims of the front, with the result s that when the glasses are worn, the material of which the temples are composed in no way interferes with the side vision of the spectacle wearer and, even while wearing the spectacles, he has at all times, without. the necessity of turning his head in order to obtain a direct vision of objects ap proaching from either side, as free and untrammeled vision of such objects as if he were at thevtime actually not wearing spectacles. Or in other words the dark field on either side, caused by the interference of the temples with the side vision of the wearer, and the resultant danger to life and limb, is entirely eliminated.

It will be seen from the foregoing that the essence of my invention consists in the raising of the points of attachment of the temples to the front to a point substantially above the points at which the horizontal plane passing through the pupils of the eyes of the wearer cuts the outer edges of the spectacle rims, and that the form of the front, or the material of which it is composed, or the form of the temples, or the material of which they are composed, or the. method ofattachment used, whereby the temples are attached to the front, are merely incidental, and may be varied to suit the individual taste or requirement of those who may wish to avail themselves of the improved method of spectacle construction embodiedherein.

The invention will be hereinafter particularly described, ointed out in the claims and illustrated in t e accompanying drawing, in which Figure 1 is a front view of a spectac'le frame, the direct view showing only a front comprising two r'ims,lugs for connecting temples and a nosepiece, the rims containing lenses, the temples broken away, and illustrating the position of the eyes of the wearer with relation to the position of the point of temple attachment on the frame front. Figure 2 is a side view of the same in position on the human head and illustrating the relative position ofthe temples and the pupils of the eyes; and Figure 3 is a rear view of the same, showing a front containing lenses, with. temples attached in a folded position.

In a detail description, in which like numerals' refer to like parts throughout the sevcral views, the lenses 10 are mounted as usual in rims 11 connected by a nosepiece 12. At.

points substantially above points at-which a horizontal line projecting through the center of thepupils of the eyes 18 intersects the outer edges of the rims 11 are laterally projecting lugs 13, to which are secured the temples 1 1, which arrangement leaves the side field of vision of the wearer clear, as

' shown in Figure 2.

The joining of the temples 14 to the lugs 13 may be any connection that will permit of the folding of the temples 14;, under as hinges 15, as shown in Figure 3. The te m. ples have squared ends 16 so that when the temples 14 are expanded for use, as shown in Figure 2, these squared ends 16 of the.

temples 14 will have a firm setting against the portions or faces 17 of the lugs 13. The lugs 13 are arranged on the temple sides of the lenses and provide temple end piece connections. Each lug 13 is disposed or located between the center of the pupil of the eye and top of the lens when in place on the face.

The under and upper sides of each lug 13 blend with the under and. upper sides respectively of that rim with which the lug isassociated. The rims in connectionlwith the bridge provide a holding means for the lenses.

The pivotal engagement of a temple with a lug is substantially throughout the width of the lug. The under side of each temple forms a continuous unbroken line at its conmotion to the lens holding means, The temples are pivotally connected to the lugs in a manner to form an acute angle between the under side of the temple and the eye side of the'lens holding means. The end ieces are on the same inclination as theo temp es form 'ing an unbroken liner Under such condi tions it eliminates the downward slipping from the bridge of the nose.

The inclination and acute angle of the temples carry the temples off of or above the wedge of the cheek bones. In the old form of spectacles the temples fell on the wedge of the cheek bones which would cause the temples to rise, lifting the ear, loops off of the ears and allowing the lenses to slip forward.

- This objection is prevented by disposing the temples at an inclination and acute angle.

' It will be noted when the spectacles are in position before the eyes the endpieces or lugs are disposed horizontally and in Figure 3 that where the axial line of each temple crosses the line of the edge of the lens when the temple is folded, the angle included between the underside of said line and the edge of the lens is an acute angle. It is clear that if the endpieces and temples were attachedin alignment with the horizontal centers of the lenses the said included angle would be ninety degrees and not acute when the temples are folded. Therefore when the endpieces and templesare moved up to the position shown the relationship of the endpieces, temples and edges of the lenses is changed in order that the temples fold-against the lenses in proper position.

It will be noted in Figures land 3 that the endpieces 13 and the bridge 12 all lie in a substantially straight horizontal line. That with reference to Figure 3' the temples 14 are provided with portions to fit behind the ears. The inner, side of thebridge 12 is adapted to bear against the face of the wearer. As the endpieces 13 are located above the pupils of the eyes and in substantial alignment with the bridge 12'it is apparent that the templesact as levers when secured behind V the ears and tend to draw'the bridge 12 against the face'to hold the spectacles in set position to prevent downward sliding thereof.

In accordance with the patent statutes I have described the principle of my invention,

to ether -with the construction which I con "faces of the rims and located substantially above the horizontal axis of the rims which passes through the center line of the pupils of the eyes, temples having squared ends and hinged to the lugs, the hinge joints being inset from the free ends of-the lugs in suchmanner that the temples will cross the front, and will have a firm setting against the flush faces of the lugs when the temples are expanded to hold the lenses at a proper angle.
